I love to find new sites.  There is a crowd sourcing site for medical related services and inventions.  It is called medstartr.com.

Please take a look at this invention.  It will communicate with a Smart Phone and inform the physician that the patient is developing significant swelling in the lower extremities.  This is an important sign of Congestive Heart Failure and can lead to earlier treatment and reduced need of more emergent care.
